dinal rows'Awill be spacedapartby spec of springs. v

The purpose ofthis invention is to provide a new and better means for connecting-the. end coils of such springs and to combine With the clip used therefor spacing rods which pass through said clips and have offset portions enclosed within said clipsso' as to holdcer of springs in the difi'erent series of. rows tain of the rows of springs apart.-

A further purpose is toprovide in a con-' struction of the character described means for making a non-movable joint between the clip and one of the springs so that the springs will not pile or rotateupon each other. V Further advantages and objects of thein; vention will appear from .the specification and claims herein. 7

V e l In the spring struoture illustrated it will be seen that the desired number of coiled spr'in'gs 10 are arranged in longitudinally: "extending rows A and transversely extend Application tied May 6, 1930.

ing rows 3-; 'For definiteness of description it w1l'l be assumed that as shownin the drawon-Iran stares P TEN fence I in'gs the end coils 11 of adjacent springs in the transverse rows B are to he conneetedby clips 12 and that the springs in thelongitufing rods 13. It will be understood ofcoui se' that in'any particular structure the spacing" rods might. extend transverse, thereof with; the clips between the springs ofthel'ongitudinal rows- It will be obvious that such; change simply involves the relative number It will be seen that the springs illustrat d in the drawings. are of thetype where the extremity of the end coil 11 is nottied'or knotted to the within or adjoining coil of the 1 extending radially outwardly from the end coil but still in the general plane of the end coil so as W 12. v j 1 The clip 12 is conveniently formedof sheet metal stampedout so'asto have a rectangu to be enclosed within th l li lar body portion 15 and two oppositelyfarranged projecting end flaps 16 and two op ositely disposed side wings 17?." A clip of't'js formislaid over the adjacent parts, of the end ooilsoftwo springs in the transverse row including the offset portion or project- I ing portion ofone of these two springsa proximately f as shown in F ig. 3. It will understood that Figs. 3 and 1 are plan views ing'rod 13. This offset 14 may be conven-' iently' formed as a V-shaped' loop formed in the wire orrod 13 although other forms of offset may be used such as a curved U-shaped "form as shown in Figs. 6. 8 and 12. It will be I seen that when the partsa're placed in posh tion ready-for assembling the offset 18 romof the joints shown'in Fig. 1 as seen from bethe right hand spring is at one side of the rectangular body portion 15 of the clip and projects part way towards the other spring. In addition to the extremity of the end 0011 having the offset 18 there is brought into the clip the-oppositely located portion 19 of the said end coil11 of said right hand spring;

Through the clip also extends the plain or slightly curved portion 20 of the end coil of the left-hand spring. With the parts in the position as shown in Fig. 3 the two end flaps are bent about the said portions 19 and 20 and towards each other and against the offset portion 14 of the spacing rod 13 so that the parts then appear as shown in Fig. 4:. Then the bent over the'inturned en side wings'17 are other so as to firmly flaps. 16 towards each hold the end flap '16 down in' positionand so as to close the twosides of the flap and hold ;the oiiset 18 of the extremity-of the right center of-thecushion. It will be understood of course thatthe offsets 1 1 in thespa-cingf rods 13 are located atfthe proper distance apart according to the distance that the transverse rows B are to be spaced'from each other.

It willbe seen that when the springs are of the form shown in Fig. 1 the clip here 11- lustrated serves to fastenthe extremity of the; end coil to the opposite adjacent portion of theend coil and avoids a separate knotting operation and also avoids the roughness or upward projections incident to a knot.

. The offset portion 18 upon theright hand spring on account of extending radially from said end coil will prevent the Y ative to the clip 12. p I plain portion 20 of. the left hand spring can rotate relative to .the said clip so'as to get springs.

the desired flexibility at these joints mak--- "connection between the right hand I V and the clip ;a substantially. non-- movable joint and prevents the springsfrom ing the piling or ,turningover each other at the w-clipped joint.

. In the modification shown in Figs. 6 and 7 theofiset 24 upon the extremity of the outer coil 11 extends inward toward the center of the .circle "and the next within coil of the spring-is spaced slightly from the end of this ,oiiset but both the offset 24 upon: the right hand spring and the, looped ofiset 25 upon the connecting rod 13 are enclosed within the" end flaps16 and sidewings 17 r of the clip 12. It will be understood that.

hold the offset 14: of the spacing a smooth surface toright hand, spring from rotating to any great extent rel- IOn the other hand the 1 springs in after the parts have been brought to the osition shown in Figs. 7 the side wings 17 will be closed over the end flaps as appears in Fig. 5. 7 The modification shown in Figs. 8'and 9 involveshavinga hole 21 in the clip 12 near the line whereone side flap is to be bent relative to the body 15 of the clip and through this hole extends the end of the outer coil 11 withthe offset 26 extending inwardly so as parts folded down over this 'ofi set and also over the ofiset 27 ofthe' connecting rod.

, In the. modification shown in Figs. 10 and 11 the oifset 22 upon the outer coil 11 to be d. enclosed within the clip is in the form of an inwardlyv extending-loop and the clip is formed proportionately longer as appearsin Fig. 11 where the clip is shown in partly closed position, that is .priorto the final overlapping of the side wings 17.

Fig. 12 shows- 23 is formed upon the body of the end coil 11 instead ofat its extremity but this ofiset extends outward from; the circle of the end. coil of the spring." The spacing bar'has a loop-shaped offset 28. p T In all of these modifications it will be seen that the ofi'setupon the connecting rod is securely enclosedwithin the clip and so. holds the. clips spaced apart the desired tance and thereby the springs that are in.

turn connected by means of the successive clips. a a

In all forms of the'invention also it will be seen that an'ofiset upon the end coil of one spring is provided in the plane of the end coil and enclosed within the clip so'that a non-rotatable joint is effected between the clip and the end coil having such offset and that this results inthe two connected springs jointed that theycannot' pile or pass one ontopof the other. Alsothe-ofi set upon the end coil of a spring when en' closed within. my form of clip prevents the end coil of that, spring from sliding either waythrough the'clip. M j I ,What I claim as'new-and desire to secure by Letters Patent isi I f V I 1. In a spring cushion constructionjthe combination of a plurality'of coiled springs arranged in longitudinal and transverse rows, a spacing rod arranged between each" adjacent pair of longitudinal rows and having an offset portion located between each pair of springs in the transverse rows,an endcoil of one of each pairof saidadjacent the transverse rows having anofiset in the plane of its coil and opposite the approaching part of the other spring and a clip connecting each adjacent pair of springs in the transverse rows, said: clip havinga. body portion and two oppositelyiocated end.

flaps and two side wings with the end flaps.

I w a modification of the. construction shown in Fig. 10 in thattlieofiset,

a spacing rod arranged between each adjacent pair of longitudinal rows and having an offset portion locatedbetween each pair of springs in the transverse rows and extending in the plane of the end coils thereof, and end coil of one of each pair of said adjacent springs in the transverse rows having an offset in the plane of its coil and opposite the approaching part of the other spring and a clip connecting each adjacent pair of springs in the transverse rows, said clip having a body portion and two oppositely located end flaps and two side wings, with the end flaps turned back towards each other over and enclosing portions of the end coils of the two springs including the said oflset portion of one of said springs and the interposed oliset portion of the spacing rod and with the side wings turn-ed towards each other against the end flaps and retaining the ofi'set portion of the spacing rod and the ofl'- set portion of the end coil within the clip.

In witness whereof I have aflixed my signature, this 31st day of March 1930.
